Nite Ize Stainless Steel S-Biner Size #1 2 Pack
I already have some of these and I just got some more. Very handy for keys - I quickly disconnect my car keys when I head out on foot and don't want the extra bulk in my pocket. I use them to clip my gym swipe cards to my workout bag. I like that they are so easy to connect/disconnect but you do have to be somewhat careful - I've had them disconnect unintentionally as well.
